To all whom it may. concer/n:

Be it known thatL-OHAELESH. MooEE, of Westfield., in the countyr of Hampden and State of Massachusetts, have invented new and useful Improvements in Hydrants; and I do hereby declare that the following is a full, clear, and exact .description thereof, reference being hadto the accompanying drawing, making a part of this specification, in which- Figure 1 represents a central vertical section of my improved hydrant. Fig. 2 is ahorizontal section ot hollow plunger. Fig. 3 is a horizontal section of hollow male nuten spindle.

The object of my invention is to produce a 'hydrant with anadjvustable plunger, that can be arranged to cover waste-hole in valve-l chamber through the warm months, and pre- -vent any egress of water through waste-hole,

and that c an also beV arranged in winter to permit all thek waterfrom nozzle to waste-hole,

after the valve'. is closed, to escape-simple and certain in its operation, cheap, durable, and easily repaired. i i l A shows the. barrel of hydrant, which may `be madebf wroughtiron pipe,*wi th\ knob L cast or soldered gon, into which nozzle Q is screwed. Ufrepresents Va caylindrical` valvechamber, open fat each end,having upon its inner side, nearfthe center, a female screw:

thread into'.` `which a corresponding male, B, which is cast` on y'spindle G, screws and operates the valve`0,to permit or prevent the iiow of water., The chamber U terminates with an extension, Ffffcast on it, on the outside of which a thread fis'.v cut of universalA pipe size.

O shows the` swivel-valve, iittedupon the extreme end .of` valveLspindle G, and secured by meansot' va brass pin, as shownf` `The valvelspindle Ghas a hollow nut, B, cast lon it, on the' outside ot' `which a thread-is made to cori respond with, and operate within,'.the female screwftlirea'd, lnear center of Avalve-chamber.

, `Upon'tlie valve-'spindle G, directlyabove the i `hollow nut B, isan adjustablehollow plunger,

E, providedjvith ftwoholes, P P, in the sides,

` into'which waterpasses and compresses circularjleatherwasher D on plunger against l smooth innersurface of valve-chamber U, in i whichit Works.. jFitted upon plungerEas a e circular.V4 leather,

`'D,y(whieh operates wastewhich projects horizontally outward, and on the top by a ring screwed on lthe end of plunger. Into the upper part ot` valve-spindle Gis formed a cylindrical chamber, V, and four oblong holes, I I I I, for the purpose of regulating the adjustment of plunger E, as substantially shown.

The hollow valve-rod b is affixed to valvespndle G and hollow spindle M oi' the handle, by means of screw-couplings t t. N represents a swivel-rod, which enters to the bottom of cylindrical chamber V in valve-spindle G, and passes vertically through the hollow valverod b and stem of handle M, and is worked by means of a screw in the top packing-nut (J, as shown. The plunger E, through which the valve-spindle G passes, and rotates in, is secured on spindle G, and to the swivel-rod N, by means of two pins, passing through holes I I I I in spindle G, into holes in swivelrod N, as substantially shown, and for the purpose specified.

In practice, the hydrant is put in by screwing the end F of valve-chamber U into a corresponding water-litting, or by connecting it with a brass coupling to lead pipe. By turning the handle K, the valve O is raised from' its seat and the water permitted to pass around the same, through the hollow nut B and plunger E, into barrel A, and out at nozzle Q.

When the valve O is raised, the plunger is also raised enough to' cover waste-hole R and prevent any escape of water; and when the valve is seated, the plunger is below the wastehole, and the water from nozzle to waste-hole is permitted to escape.

By putting a pin into the hole j, near the top ot swivel-rod N, and turning the same to its limits, the plunger E is raised enough to cover the waste-hole R, (without opening the valve,) and prevent any egress of water, either when valve is open or shut.

By unscrewing the cap El from the body of hydrant, and turning the hollow nut B from its place, the valve can be easily lifted out for repairs.

rlhe especial advantages possessed in this hydrant are, by adjusting'the plunger and covering the'waste-hole-to prevent any egress ofwater through the same for seven or eight months, when there is no danger from frost-first, you economize greatly in the use of water; second, when the waste-hole is covered, the hydrant is always full, and you get Water upon the instant of raising valve; third, the ground around the valve being kept dry for seven or eight months, is much better prepared to contain the water that is necessary to waste through the cold season, than if there was always a waste after using, as is generally the case fourth, the hollow plunger, having holes in the sides, permits the water, when passing through it, to press circular leather washer on plunger against waste-hole, making it perfectly secure from any leakage when valve is open 5 fth, the device is very simple in construction, exceedingly durable, and not liable to get out of order.
